Patent number: 10507273Abstract: A method of filling a container, preferably containing at least one concentrate, with the concentrate being formed such that it forms at least one liquid concentrate or a part of a liquid concentrate on its solution in or its mixing with a liquid, preferably water, the liquid concentrate or the part of the liquid concentrate being suitable for preparing at least one dialysis solution, includes filling the container via a balance chamber system of a dialyzer. The balance chamber system has chambers from which the liquid is conveyed into the container in the form of repeating cycles. The pressure of the liquid being conveyed is measured during a cycle of the filling phase of the container, and an alarm signal is emitted and/or the filling of the container is stopped if a measured maximum pressure in a cycle does not reach or does not exceed a limit value.Type: GrantFiled: May 7, 2015Date of Patent: December 17, 2019Assignee: FRESENIUS MEDICAL CARE DEUTSCHLAND GMBHInventors: Peter Kloeffel, Olaf Nicholas

Patent number: 9265874Abstract: A method provides for the production of a concentrate for dialysis, the composition of which can be adapted individually to the respective needs of the patient. The special components required individually are added in the form of highly concentrated special concentrates with a volume of 10-500 mL to 3-10 liters of standard concentrate. The two solutions are then mixed thoroughly by compressed air, which is blown through a concentrate intake rod into the solution from a compressed air source in the dialysis machine.Type: GrantFiled: January 9, 2012Date of Patent: February 23, 2016Assignee: FRESENIUS MEDICAL CARE DEUTSCHLAND GMBHInventor: Peter Kloeffel

Patent number: 9119922Abstract: The invention relates to an apparatus for extracorporeal blood treatment, comprising a device for detecting a tubing system to be placed in the blood treatment apparatus and a method for detecting a tubing system to be placed in an extracorporeal blood treatment apparatus. The tubing system is detected on the basis of the dependency of the flow rate Q, at which the fluid is delivered by at least one pump of the extracorporeal blood treatment apparatus in a tubing section of the tubing system, on the speed n at which the at least one pump is operated, and on the inner diameter d of the tube of the tubing section. Because the dependency of the flow rate on the pump speed and the tube cross section is known, a conclusion can be drawn as to whether a particular tubing system has been placed in the extracorporeal blood treatment apparatus.Type: GrantFiled: May 15, 2010Date of Patent: September 1, 2015Assignee: Fresenius Medical Care Deutschland GmbHInventors: Thomas Nuernberger, Peter Kloeffel

Publication number: 20120212455Abstract: The invention relates to the field of technical medical devices, for example, dialysis machines. The object of the invention is to improve upon a technical medical device in such a way that the structural complexity of the technical medical device, the assembly, cleaning and maintenance expense for the technical medical device and the cost of the technical medical device are reduced, but at the same time the variety of functions increases. The technical medical device according to the invention therefore comprises a screen, which can be equipped to function as a sound converter or as an optical sensor or as a receiver and sender of electromagnetic waves. In addition, a method is disclosed whereby the control of the technical medical device is influenced on the basis of the input and output of information via the inventive display screen.Type: ApplicationFiled: February 17, 2012Publication date: August 23, 2012Inventor: Peter KLOEFFEL
